Disable the PCIe bus in the default device tree to avoid shared
regulator conflicts between SDIO and PCIe buses. The non-deterministic
probe order between these two buses can break the PCIe initialization
sequence, causing PCIe devices to fail detection intermittently.
On i.MX95-15x15 EVK board, the M.2 connector is physically wired to both
USDHC3 and PCIe0, however the out-of-box module is SDIO IW612 WiFi, so
enable SDIO WiFi in the default imx95-15x15-evk.dts.
Add 'm2_usdhc' label to USDHC3 to support device tree overlay for PCIe
modules. Users who need PCIe can use imx95-15x15-evk-pcie.dtb (added in
a follow-up patch) which applies an overlay to enable PCIe and disable
USDHC3.

On the Toradex SMARC iMX95, the WiFi UART signals are shared with the
JTAG. The WIFI_UART_EN signal is used to select between these
two functions. A GPIO hog is used to select the UART function by
default. This DT file is going to be used by both Linux and the boot
firmware, and the boot firmware will configure the GPIO hog way before
the Linux kernel is booted, therefore there is no actual race condition
between the Linux kernel BT UART driver and GPIO hog probe.
